But aside from the obvious titular inferences we can make in "Ruin the Friendship," the lyrics definitely points to finally acting on a certain longtime chemistry. Because though Nick and Demi have never publicly disclosed having a romantic relationship, Noisey points out that there may be a reference in the lyrics that hints at Nick being this person Demi speaks of. "Put down your cigar and pick me up," the first verse begins. "I'm thinking we should cross the line/Let's ruin the friendship," the chorus echoes. Noisey points out that is Nick is a well-known lover of cigars.

Demi then goes on to explain that with "Ruin the Friendship," she "was frustrated with a certain situation."

"And I was like, 'You know what, I'm just going to write about it.' And so I did, and sent [the songs] to that person, and that was... interesting," she continued. "Any time you send a song about the person, to the person, it's ballsy. It's like, 'Hey! Here's my feelings for you!' … They knew [about my feelings], but neither of us had acknowledged [them] before. And then it turned out that person had written a song about me, and we exchanged songs."

So... does that mean that if it's about Nick, he feels similarly about her? And has the exchanged song in question been released yet? Naturally, this has sparked much fan speculation.
